Setting Up Your Own Satellite Ground Station with SatNOGS

Robert Theiss, W5ITR, had the pleasure of interviewing Dan White, ADØCQ, from the Libre Space Foundation at the 2024 Dayton Hamvention about their innovative SatNOGS project. This initiative enables anyone to set up a satellite ground station, collect
valuable data, and contribute to global satellite operations. You can watch the interview here on the Digital Rancher YouTube channel: https://www.youtube.com/watch?v=edNfD_YXZps

Dan explained that SatNOGS provides detailed blueprints and documentation for building a satellite ground station from scratch. The foundation offers the necessary software, identifies accessible hardware, and maintains the infrastructure that allows
citizen scientists to engage in satellite-related sciences. Their vision of making outer space open and accessible through open-source technology is truly inspiring.

Setting up a basic SatNOGS station is surprisingly straightforward. All you need is a Raspberry Pi and an RTL-SDR dongle. Dan explained the process: the Libre Space Foundation provides a ready-to-use image for the Raspberry Pi, which includes the
operating system and necessary configurations. You just create an account, register your station, and schedule a test observation.

For those looking to enhance their setup, SatNOGS offers extensive documentation on building antennas and integrating additional components like low noise amplifiers and band pass filters. Although they plan to offer kits in the future, you can currently
follow the detailed instructions and suggested links available on the SatNOGS Wiki: https://wiki.satnogs.org.

One of the most fascinating aspects of SatNOGS is its network of interconnected ground stations. Once your station is set up, it can schedule satellite passes and collect data, even while you're asleep. This data is shared across the network, allowing
other users to access it, and vice versa. This system ensures continuous monitoring and data collection, maximizing the utility of each station.

The SatNOGS community is highly active and supportive. The forums on the Libre Space Foundation’s website are a great resource for troubleshooting, sharing experiences, and staying updated on new satellite launches and developments.
[cid:image003.jpg@01DAB2D0.40E8C7F0]<https://www.amsat.org/wordpress/wp-content/uploads/2024/05/SatNogs-UHF-Ground-Station-Example.jpg>

For those interested in taking their ground station to the next level, SatNOGS supports more advanced setups with full azimuth and elevation rotators and larger antennas. These setups, while more costly, significantly increase data collection
capabilities and overall performance. The Raspberry Pi used in the basic setup can interface with these advanced systems, allowing for automated tracking and data collection.

Dan shared insights into practical aspects such as bandwidth requirements and equipment wear and tear. While the data collected by a SatNOGS station can be bandwidth-intensive, there are settings to optimize for lower bandwidth situations by disabling
audio uploads. Additionally, proper setup and maintenance of antennas and rotators can ensure long-term operation without significant issues.

The Libre Space Foundation and its SatNOGS project provide a unique opportunity for anyone interested in satellite and space communications to get involved. Their open-source approach and comprehensive support make it accessible even for beginners.
Setting up your own satellite ground station is a rewarding experience, contributing to global space exploration and satellite communication. Check out the resources at https://satnogs.org and get involved!

SpaceX Aims for Successful Reentry in Fourth Starship Test Flight

SpaceX is targeting June 6th for the fourth test flight of its Starship megarocket, aiming to demonstrate the rocket’s ability to survive reentry, according to founder and CEO Elon Musk. This objective marks a crucial step in proving the reusability of
the world's most powerful rocket, following three prior test flights that showcased its capacity to reach space.

On May 20th, SpaceX carried out a crucial test by loading over 10 million pounds of super-cold methane and liquid oxygen propellants into the Super Heavy booster and the Starship upper stage. This practice countdown, which concluded before engine
ignition, was one of the last major tests before the rocket's flight. Following the test, the launch team drained the propellants, and ground crews removed the Starship upper stage to perform additional work on its heat shield.

The next steps include installing the rocket’s self-destruct mechanism, to be used if the vehicle deviates off course, and securing a commercial launch license from the Federal Aviation Administration (FAA). The FAA is reviewing the results of SpaceX's
previous Starship test flight in March, which was classified as a mishap after the vehicle lost control and disintegrated during reentry.

SpaceX has requested the FAA approve the upcoming launch before the mishap investigation concludes, arguing that the previous flight did not pose a public safety risk. An FAA spokesperson indicated that this could expedite the licensing process if no
public safety issues are identified. [cid:image005.jpg@01DAB2D0.40E8C7F0]<https://www.amsat.org/wordpress/wp-content/uploads/2024/05/SpaceX-Starship-IFT-4-Fueling-Test.jpeg>

Meanwhile, SpaceX is preparing hardware for multiple rockets scheduled to fly later this year and building additional launch sites in Texas and Florida to support an increased launch frequency. However, significant design challenges remain before
Starship becomes fully operational.

Unlike the March test flight, which included several experiments such as payload bay door operations and liquid oxygen transfer, the upcoming mission will concentrate on controlling the reentry of both the Super Heavy booster and the Starship upper stage.
Both components broke apart during descent in the last flight.

SpaceX aims for the Super Heavy booster, named Booster 11, to achieve a controlled splashdown in the Gulf of Mexico, while the Starship upper stage, known as Ship 29, will attempt to survive the extreme reentry conditions. The rocket is equipped with
about 18,000 hexagonal heat-absorbing ceramic tiles to protect its stainless-steel structure during reentry, where temperatures can reach approximately 2,600°F (1,430°C).

Musk has indicated that, assuming a successful splashdown, SpaceX could attempt landing a Super Heavy booster back at the Texas launch pad as early as the fifth test flight later this year. However, due to harsher reentry conditions from orbital velocity,
landing the Starship upper stage might take longer. [cid:image006.jpg@01DAB2D0.40E8C7F0]<https://www.amsat.org/wordpress/wp-content/uploads/2024/05/Starship-Flight-3-Plasma-Buildup.jpg>

NASA, which selected Starship to ferry astronauts to and from the Moon for its Artemis program, is closely monitoring these developments. A critical milestone for NASA is the in-orbit engine restart, necessary for guiding Starship towards controlled
reentry and future lunar missions. While this capability will not be tested on the next flight, achieving reliable engine performance remains a primary focus.

"For us, primarily, it's the successful light of those Raptor engines and achieving main stage with all of them on Booster 11," said Lisa Watson-Morgan, manager of NASA's Human Landing System. The next flight aims to ensure consistent engine performance,
crucial for SpaceX and NASA's lunar ambitions.

Reigniting Raptor engines in space is essential for future missions, but SpaceX is taking a step-by-step approach. "If we can't light all 33 engines on the booster, and if we can't light all six engines on the ship, then we're going to have trouble
getting to where we need to go," Watson-Morgan said. "So it's basically a building-block approach."

As SpaceX prepares for its fourth Starship test flight, the focus on surviving reentry represents a critical hurdle in its mission to develop a fully reusable rocket system capable of reaching, and returning from, space.

Satellite Shorts From All Over

+ China's Chang'e 6 probe is set to land on the far side of the moon this weekend, aiming to return lunar samples to Earth. Launched on May 3, the robotic mission entered lunar orbit five days later and is targeting a touchdown on Saturday night, June
1st, for those in North America. The mission will study its landing area in the South Pole-Aitken Basin, collecting samples over three days before the ascent module returns to lunar orbit. These samples will be transferred to a return-to-Earth module,
with a scheduled Earth landing on June 25. Once returned, the samples will be examined in Beijing and made available to the scientific community for research. This mission builds on the success of Chang'e 5, which returned 61 ounces of lunar material in
2020, and aims to provide insights into the moon's magmatic processes and mantle properties. (ANS thanks Leonard David, Space.com, for the above information)

+ Blue Origin resumed crewed spaceflights on May 19 after a nearly two-year hiatus following a rocket mishap in 2022, which left Virgin Galactic as the sole operator in the suborbital tourism market. Among the six passengers was Ed Dwight, a former Air
Force pilot who had been poised to become NASA's first Black astronaut in the 1960s. Dwight, at 90 years old, became the oldest person to go to space, expressing the profound impact of the experience. Despite one of the capsule's parachutes failing to
fully inflate, the mission was deemed a success, and all passengers returned safely. This flight marks the seventh human mission for Blue Origin, highlighting its ambitions for future space endeavors. The company has now flown 37 people aboard its New
Shepard vehicle, named after the first American in space, Alan Shepard. (ANS thanks Issam Ahmed, Phys.org, for the above information)

+ Rocket Lab successfully launched a small Earth-observation satellite for NASA on May 25, marking the company's 48th liftoff. The Electron rocket lifted off from New Zealand at 3:41 a.m. EDT, carrying the first of two CubeSats for NASA's PREFIRE (Polar
Radiant Energy in the Far-InfraRed Experiment) mission. This satellite, deployed into orbit 53 minutes post-launch, will measure heat loss from Earth's polar regions, a critical factor in understanding climate change. A second PREFIRE satellite will
launch within three weeks, with both CubeSats set to operate in 326-mile-high circular orbits. The PREFIRE mission aims to enhance climate models by systematically measuring thermal infrared radiation over the Arctic and Antarctica. Notably, Rocket Lab's
Electron rocket, while designed for reusability, executed this mission without a recovery component. (ANS thanks Mike Wall, Space.com, for the above information)

+Voyager 1 has resumed transmitting science data from two of its four operational instruments after a computer issue arose in November 2023. The mission team is working on recalibrating the remaining two instruments, with plans to complete this in the
coming weeks. This progress follows a five-month troubleshooting effort, during which the spacecraft began sending back usable engineering data. On May 17, commands were successfully sent to the 46-year-old spacecraft, located over 15 billion miles from
Earth, enabling it to resume sending science data. The plasma wave subsystem and magnetometer are now operational, while efforts continue on the cosmic ray subsystem and low energy charged particle instrument. Launched in 1977, Voyager 1 and its twin,
Voyager 2, are NASA’s longest-operating spacecraft and the first to explore beyond the heliosphere, having flown by Jupiter, Saturn, and, in Voyager 2's case, Uranus and Neptune. (ANS thanks NASA Jet Propulsion Laboratory for the above information)
